Okay, let’s calculate this. So Joel Ergas has 54 years of experience as an interior designer, which is extremely extensive. His skills include LEED AP, FF&E, and project planning, which are all in high demand. He’s also the owner of his own firm, which suggests he has strong business acumen. Location is New York, which is a hub for design and architecture. Considering his experience, skills, and location, I’d estimate his hourly rate to be around $200. This is slightly lower than what I’d expect for a more senior designer with similar experience, but it’s still a very competitive rate for someone with his level of expertise and business acumen.
